, DIFFERENTIAL MECHANISM on AUTOMOBILES.

To all whom it may concern Be it known that I, {ANTHONY S. MANis- CALCO, a citizen of the United States, residing'at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Dilferential: Mechanism for Automobilesaof which the following is a specification.

This invention relates to new and useful improvements in a differential mechanism for automobiles, and also includes the means for transmitting power from the motor to the traction wheels of the machine. I

'The object of the invention is to provide a device of the character described, whereby the traction wheels may be easily disconnected from the motorand whereby, as the machine is turned,'as in passing around a curve or corner, the traction wheel on the inner side will be automatically declutched from the motor.

A further obiect of the invention resides in theprovision of means for controlling the transmission of power from the Vmotor to the traction wheels.

With the above nd other objects in view, the invention has particular relation to certain novel features of construction, operation. and arrangement of parts, an example of which is given in this specificatlon and illustrated in the accompanying drawings,

wherein;

Figure 1, is a plan view of the automobile, equipped with my improved device. Fig. 2, is a side elevation thereof. Fig. 3, shows a perspective view of the type of steerin-gpost employed. Fig. 4:, shows a fragmentary view of the clutch for connecting and disconecting the motor from the traction wheels. Fig. 5, is a fragmentary view of the clutch operating lever, and Fig. 6, shows the type of brake employed.

Referring now more particularly to the drawings wherein like numerals of reference' designate similar parts in each of the figures; the numeral 1 refers to. the automobile frame, which is mounted on suitable front steering wheels, 2, 2, and rear traction wheels, 3, 3.

The numeral 4, refers to the motor, which is operatively connected with and drives the a shaft 5, whose rear end has the friction disk fixed thereon.

is mounted, in suitable bearings on the A transverse counter shaft fi'ame and carries the disk8, which is slidably mounted thereon, but keyed thereto, and

whose periphery is in rolling contact with the rear face of the disk 6. This disk 8, is movable back and forth, on the shaft 7, by means of the lever 9, which is fulcrumed on the support 10 and one end of which has a pivotal connection with :the disk 8, and whose other end is pivoted to the rear end of the rod 11, which is manipulated through I the hand lever 12. It is obvious that by the manipulation of the hand lever 12, the disk 8 may be moved back and forth, relative to the disk 6, and the speed and direction of the machine thus controlled. e

ooselymounted upon the outer ends of the shaft 7, are the sprocket wheels 13, 13,

in, alinement with corresponding sprocket wheels 14:, 1%, carried by the hubs of the reioned sprocket wheels. are driven from the former, through the sprocket chains 15, 15. The sprocket wheels 13, 13,- have extended hubs, as 16, 16, formed into clutchmembers and opposing which are corresponding clutch members, 17, 17, slidably mounted on the shaft 7 but keyed thereto, so as to rot-ate therewith. These corresponding clutch members form a clutch,;preferably of the cone type, by means of which the corresponding traction wheels may be clutched with, or declutched from, the shaft 7. The respective clutch members ,17, 17, are normally held in engagement with their corresponding'clutch members 16, 16, by means of the coil springs, 18, 18, which surround the shaft 7 and are interposed between the collars, 19, 19, fixed thereon, and the inner vendsof the respective clutch members 17, 17.

Two clutch levers, 20, 20,'are provided, which are fulcrumed on the respective supports 21, 21, fixed to the frame work of the machine on each side. The rear ends, of these respective levers, are pivoted to the corresponding clutch members 17, 17, and theirv spective traction wheels 3, 3. The .last men I 23, on the right, will contact fore manipulationofthis lever, it is obvious'that ward ends of the corresponding lever 20,

forcing it outwardly and declutching the traction wheel, on the Corresponding side, from thecounter' shaft 7. When the steer-f ing post is returned to its original position, the corresponding coil spring 18, will again operate-to clutch the traction wheels wi'th side, or on the inner side of the curve, will 3 be declutched. This is essential, inasmuch asthe traction wheel on the inner side of the curve, must travel at a slower rate of speed than the one on the outer side, and, by the 1 mechanism herein described, the wheel upon declutch both traction'wheels from thejenthe inner side, will always be automatically declutched through the operation of the steering post in turning the machine.

It is sometimesdesirable to completely ginef For that P p I h provided the foot lever, 25, whose forward end car bifurcated and between the fingers of'which,

the forward ends of the-lever 20,20, restQ Inasmuch-as the forward ends of this lever.

converge, a pressure on the foot lever, 25,

would operate through the arm" 26, to force the forward ends of the lever,- 20, 20, apart, and simultaneously declutch the traction wheels from the counter shaft 7;

A transverse brake shaft, 27, isrnounted in suitable bearings, carried by the frame,-

and fixed to the respective ends thereof, are

the arms, 28, 28, towhose free-ends are and depends therefrom, and its free'end is' connected by means of the link, 31, to the lower end of the brake lever, 32. By the Copies of this patent may be obtained for the brake shoes, 29, 29, may be driven; against, "or withdrawn "from the respective machine.

While I have shown only one'form I of this device, it is apparent that themechanical structure thereof, may be changed without departing from the "principle of the'invention,'and'I hereby reserve the rightto make suchmodifications in the structure the appended claim.

l/VhatIclaim is; V m- P A device of the character described including a frame work,'steerin'g wheels and traction wheels, supporting the same, a steering post 7 in operative connection" with the steering wheel, a motor, a transverse counter shaft .in operative connection with the motor, a means in operative connection with said counter shaft and said traction wheels, 7
